What it is
Simon Smith (@_simonsmith) posted that he has now created two personal apps in ChatGPT. He used his Dot to create the backend in ChatGPT Sites as an MCP server and the frontend as a plugin with extensions. The news app has a customizable feed with thumbs-up and thumbs-down feedback, and he can discuss an item with ChatGPT inside the app. The Spanish vocab app imports words he highlights in Spanish books on his Kindle, then he learns them with flash cards and quizzes. He says the Dot hides the complexity and "babysits" the build: when he tried the same app in a Work thread directly, it did not work, but his Dot tested it until it worked. He also lists improvements he wants: the Dot needs reminders to add proper sidebar icons, cannot change the plugin version label from v1.0.0, has struggled to fully test plugins, and does not show what it is doing.

Caveats
- The poster’s X post only. This page does not add details the post does not state.
- Not a verified independent case study. Not an OpenAI statement.
- The post also lists problems, for example icons, the plugin version label and limited testing. This page does not judge them.
- The poster says Muse was faster on the same app and Claude did about as well. This page does not compare products.
